It is also important when using a base/clear process to have same brand/system because the thinners are unique and proprietary quite often. That goes for spray cans and automotive paint. Assuming the weather is warm and the rim is warm to the touch, the primer will be cold until it is dry. You can touch it before hand without leaving a finger print, but if it still feels cold than it is still evaporating. That is the method I use at work everyday since I work with primer continually and I can't be smelling it for dryness without some weird side-effects,

It sounds like overall, the problem was lack of dry time. If you have reflectors off and tires off, you can aim a space heater (or similar heat source) at it to accelerate the cure. Usually enamels would be baked at 120-180 deg for about a half-hour in a production environment. Adjust accordingly.
